Sometimes you want to remember some value that was the output fromm one table, and use it as an input to another.  For example, let's say you added a record to a database, and the database automatically generated a key to that record.  Let's say that in another table you wanted to use that key to fetch the record back.  You can use ''symbols'' for this.

!|SaveRecordInDatabase|
|name|date |=key?  |
|Bob |today|bobKey |
|Bill|later|billKey|

In this table two records are added to the database.  The keys for each record are saved in symbols named ''bobKey'' and ''billKey''.  The ''=key?'' header indicates that the output of the ''key()'' method of the fixture is to be stored in a symbol whose name is in the cell.

!|FetchRecordsFromDatabase|
|key=   |fetch()|name|date |
|billKey|true   |Bill|later|
|bobKey |true   |Bob |today|

In this table the two keys are used to fetch the database records.  The ''key='' header indicates that the value of the symbol whose name is in the cell should be stored in the ''key'' variable of the fixture.
